Abstract

Background

Helicobacter pylori (H. pylori) is the major cause of gastric mucosal precancerous lesions in adulthood, but its impact on pediatric patients remains unclear. We aimed to investigate H. pylori-induced gastric precancerous lesions in children and adolescents globally and analyze their influencing factors for related disease management and prevention.

Materials and Methods

We conducted a comprehensive literature search in major databases to identify studies including pediatric patients with gastric precancerous lesions and H. pylori infection status. Prevalence rates were computed using random-effects or fixed-effect models. A stratified analysis was conducted based on location, age, universal health coverage (UHC), and publication time.

Results

Among the 3359 relevant articles screened, 24 studies (7036 participants) met the inclusion criteria. The overall prevalence of precancerous lesions in H. pylori-infected patients was 17.2%, in which atrophic gastritis (AG) and intestinal metaplasia (IM) were 13.5% and 3.6%, respectively. Precancerous lesion rates in infected individuals across different regions were as follows: Africa at 33.8% (AG: 32.6%), Latin America at 22.1% (AG: 17.9%, IM: 4.0%), Asia at 18.1% (AG: 12.4%, IM: 4.4%, Dysplasia: 1.2%), and Europe at 6.3% (AG: 4.3%, IM: 1.7%). Infected adolescents (> 10 years) exhibited a higher prevalence of precancerous lesions than younger children (≤ 10 years) at 14.2% (AG: 9.7%, IM: 2.9%) versus 3.4% (AG: 2.3%, IM: 1.1%), respectively. The prevalence of precancerous lesions in infected patients was higher in areas with low-medium UHC compared with high UHC (24.0% vs. 12.5%).

Conclusions

H. pylori infection causes significant gastric mucosal precancerous lesions in pediatric patients, representing a major concern for this population and a previously neglected area. Future in-depth investigations and proper management for related disease prevention are warranted.

期刊介绍： Helicobacter is edited by Professor David Y Graham. The editorial and peer review process is an independent process. Whenever there is a conflict of interest, the editor and editorial board will declare their interests and affiliations. Helicobacter recognises the critical role that has been established for Helicobacter pylori in peptic ulcer, gastric adenocarcinoma, and primary gastric lymphoma. As new helicobacter species are now regularly being discovered, Helicobacter covers the entire range of helicobacter research, increasing communication among the fields of gastroenterology; microbiology; vaccine development; laboratory animal science.
